AUGUST F. BAUER, OF KANSAS CITY, MISSOURI.

GAS OR VAPOR STOVE.

To all whom it may concern:

Be it known that I, AUGUs'r F. BAUER, a citizen of the United States,and a resident of Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements in Gas orVapor Stoves, of which the following is a specification.

My invention relates to improvements in stoves.

- It is particularly adaptedfor use in connection with gas or vaporburners.

The object of my invention is to provide a stove in which gas orhydrocarbon fuel may be economically burned and. with intense heatingeffect.

A further object of my invention is to provide a construction which isstrong, durable and cheap to manufacture.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings illustrating my invention-Figure 1 is acentral vertical sectional view of my improved stove. Fig. 2 is a crosssection on the dotted line 42-?) of Fig. 1. Fig. 3 is a cross section onthe dotted line c-cl of Fig. 1. Fig. 4 is a cross section, partly brokenaway, taken on the dotted line ef of Fig. 1. Fig. 5 is a bottom view ofthe ring which supports the outer shell.

Similar characters similar parts.

1 denotes a horizontal base provided with one or more vertical holes 2and having downwardly extending supporting legs 3, each provided on itsinner side with a lug 4 for supporting a horizontal, circular guard 5,which is disposed below the openings 2. The guard 5 is preferably of aconcavo-convex form, the upper side of which is the concave side. Theguard 5 protects the floor from the heat emanating from a gas or vaporburner 6 mounted upon the upper end of a supply pipe 7, which extendsvertically through holes provided therefor in the guard 5 and base 1. Avertical inner shell or tube 8, preferably having upwardly convergingwalls, encircles the burner 6 and openings 2 and has its lower endfitted to the inner of two annular, concentric flanges 9 and 10, withwhich the upper side of the base 1 is provided. A vertical tube 11encircles the supply pipe 7 and has its lower end supported upon theupper side of the base 1, the upper end supporting the burner ofreference denote Specification of Letters Patent.

6 and supply pipe 7. Mounted upon the upper end of the tube 8 is ahorizontal ring 12 having 011 its under side an annular flange 13, inwhich is fitted the upper end of the tube 8. An inverted cup-shapedouter shell encircles the upper portion of the tube 8. This outer shellcomprises preferably a vertical outer tube 14, which converges upwardlyand is secured at its upper end to a cap 15, supported above the tube 8by peripheral lugs 16, provided on the ring 12, which lugs are disposedin an annular groove 17, provided on the lower end and inner side of thecap 15. Transverse holes 18, are provided in the tube 14 adjacent thelower end thereof. An annular flue space 19, is provided intermediatethe tubes 8 and 14.

The tubes 8 and 14 are inclosed by a casing comprising a vertical tube20, having its upper end closed by a head 21, provided with a verticaltubular portion 22, with which, if desired, a pipe, not shown, may beconnected for carrying ofl the products of combustion. The tube 20 isprovided preferably with transverse holes or perforations 23. The lowerend of the tube 20 encircles and is secured to the annular flange 10 bythe bolts 24.

In the operation of my invent-ion the heated products of combustion,mixed with air entering the tube 8, through the openings 2, pass throughthe ring 12, into the cap 15, and thence down the flue space 19 into thetube 20, and from thence into the smoke pipe, not shown, through thetubular portion 22, when a smoke pipe is employed. When a smoke pipe isnot employed the products of combustion, mixed with heated air, willpass from the tube 20 through the openings 23 and 22.

With the inner and outer shell and the burner disposed as shown in thedrawing, the greatest heat is centered in the cap 15 which quicklybecomes red hot. By reason of the downwardly flaring form of the tube14, the heated products of combustion passing from the upper end of thetube 8 and cap 15, freely expand, thereby eflecting a strong downwardcurrent through the flue space 19. The momentum of this downwardlymoving current of heated air and products of combustion, carries suchheated air and products of combustion downward toward the base 1 and incontact with the lower end of the tube 20. These parts becoming highlyheated heat the air adjacent the floor.

25 denotes a central vertical opening in the head 21, which is normallyclosed by a cover or closure 26. This closure may be removed when it isdesired to have a pipe, not shown, connected with the outlet opening 25for conveying heat to an upper room.

Various modifications of my invention may be made, within the scope ofthe appended claim, without departing from its spirit.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

In a stove, the combination with a horizonta-l base having one or morevertical openings, of a vertical, upwardly converging tubesupported,upon said base and encircling said openings in the base, aring supported upon the upper end of said tube and having peripherallugs, a cap supported by said lugs above the upper end of said tube, andan upwardly converging outer tube encircling the first named tube andhaving its upper end secured to said cap.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
